commit badf1f2724d430c8a310be549b49f8333817dbeb (HEAD -> drm-intel-next-queued, drm-intel/for-linux-next, drm-intel/drm-intel-next-queued)

    drm/i915: Order assert forcewake test
    
    Read the current value before computing the expected to ensure that if
    the timer does complete early (against our will), it should not cause a
    false positive.
    
    v2: The local irq disable did not prevent the timer from running.
